For brands
The fitting room, on your product page.
Paste any product link. You’ll get the size off the brand’s real chart, then see the piece on a real body. Try it before you read a word of the pitch. One button on your product page does the same for your shoppers, and you only pay if it beats a control group.
Two numbers and your fit taste, read off a real size chart. Free, no account. Try it on your photo after.
This is the real engine, not a mockup. It’s reading a real brand’s size chart, live.
What just happened
That was CHECK. It’s two things.
A real fitting room answers two questions. Is this my size? And does it look right on me? On your product page they ship behind one button, but each one stands on its own. Try them separately, right here. No account, no quiz, no mockups.
An S here isn’t an S there, so nothing is guessed from the letter you wear elsewhere. This reads a real brand’s chart in centimetres, and the letter is just the answer.
The size answer. It runs alone too, as the page your size-guide link opens.
01 / 02
This is the live demo. Upload a photo to see it in action.
The fit visual. The piece on a real body, a model’s or your own photo.
Take one or both. Together they’re the fitting room. Apart, the size answer is the returns tool and the fit visual is the reason shoppers stay.
The pilot
You only pay if it moves the numbers.
We split your traffic from the first page load. Half your shoppers see CHECK, half don’t. That half is the control, so the lift is real and causal, not last-click guesswork.
We agree the bar before day one: add-to-cart lift, checkout lift, returns down. Whatever number you’d defend to your own team, that’s the one we use, and you read it off the same dashboard I do. If it clears the bar, we keep going, a monthly base plus a share of the lift. If it doesn’t, we shake hands and part ways.
Going live
No code to try it. A link to go live.
You never touch code to see if it works, and day one can be as small as swapping a link. Here’s the whole path.
01
Send me your store link
I build a live demo from your own products and send you back a hosted page. Nothing on your site, no code, no dev ticket.
02
Show it around
Open the page, try it on yourself, put it in front of whoever signs off. Still nothing installed, still no risk.
03
Go live with a link, or a line
Day one is zero code on any platform: your size-guide link points at your CHECK page instead of a static chart. When you want the button on the product page itself, it’s one line in your <head>. Which products it goes on, and where the button sits, we decide together, not through your dev backlog.
Under the hood
It knows what a slip dress is.
Everyone knows an S at one shop is an M at the next. So CHECK never reasons in letters. It works in centimetres, matching your shopper’s measurements against the garment’s actual dimensions off your chart. Only at the very end does it translate back to a letter, in your sizes, not anyone else’s.
A fitting room that guessed the same for every garment would be useless. CHECK reads the construction straight off the product photo. A slip drapes from the strap, an elastic waist gives a few centimetres, a knit is meant to sit close, a blazer lives or dies at the shoulder. Nine cuts in all, each one sized against your real chart. Twenty-nine brands charted so far.
Then it learns. Over the first month or two it calibrates to how your brand actually fits, from your own return data. Your M stops meaning the chart’s M and starts meaning yours.

Just me. Josef, in Gothenburg.
CHECK is one person. The brand side and the technical side are the same desk, so you get my direct line. No account manager, no portal. Photos are stored in the EU, faces hidden, deleted on request, never used to train anything. GDPR, all of it.
It started as a consumer app where Gen Z already try clothes on themselves over at checklook.me/vibes, so your shoppers already know the gesture the moment they see it. Tell me which categories you’d want me to validate and I’ll come back with a sample render off your own catalog.
